We just bought a "new" truck and it has that light bar on it and going to a federal signal Smart siren sm and its set up is weird! I was wondering about a wiring diagram cause bottom half of the bar is not working and also the siren is weird! When I turn on to slide 1, stuff in the slide 3 spot comes on! And yes its a horrible wire job as I am going to correct all their mistakes! Any help appreciated!
